This is hardly Mozart at his most profound. Both works were written for summer entertainment and display the teenage composer's precocious talent to amuse and divert in a succession of perfectly crafted marches, minuets and rondos. The Colloredo serenade actually amounts to a symphony and a violin concerto in one, with Alexander Janiczek playing superbly while directing from the violin. The Scottish Chamber Orchestra play this light, insubstantial fare with style and wit, but it is a little like gorging on cream cakes, leaving you feeling distinctly queasy.
